Pressure transmitter is a pressure sensor with the output as the standard signal, it is a kind of instrument that accepts the pressure variable to be converted to the standard output signal according to the scale. It can feel pressure sensor of gases, liquids and other physical pressure parameters change into standard electric signals (such as 4 ~ 20mADC), to supply the indication alarm device, recorder, regulators and other secondary instrument measurement, instructions and process control.
Basic introduction
Remote differential pressure / pressure transmitter is used to prevent the pipeline in the medium directly into the pressure sensor module in the transmitter, it between the transmitter and is by filled with fluid capillary connected to the. Used to measure the liquid, gas or steam liquid level, flow and pressure, and then change it into 4 ~ DC 20mA signal output.
1151/3351DP/GP differential pressure / pressure transmitter with remote seal device has become 1151/3351DP/GP remote differential pressure / pressure transmitter, it still has BL1151/3351DP/GP differential pressure / pressure transmitter of various characteristics. Can communicate with the HART hand operator, through its setting, monitoring.
The measuring method can avoid the contact of the isolated diaphragm of the sensor, which is suitable for the following situations:
1, the measured medium is sensitive to the transmitter sensor
2, need to be measured medium and transmitter isolation
3, the measured medium is a solid suspended solids or high viscosity media
4, the measured medium is easy to cure or crystallization from the cited pressure tube
5, the replacement of the test media to be strictly purification measurement head
6, the head must be kept clean, no pollution. Use of an object: corrosive or viscous liquid
Note: vacuum situation should not use remote transmitter.
